How effective is Vigabatrin for infantile spasms?

Sabril (generic name: vigabatrin) is an inhibitor of GABA aminotransferase. It irreversibly inhibits GABA aminotransferase, leading to increased levels of GABA (γ-aminobutyric acid), an important inhibitory neurotransmitter, in the central nervous system. GABAcan help control convulsive attacks by reducing overexcitability of neurons.

Vigabatrin has shown efficacy in some clinical trials in patients with refractory epilepsy. For example, in a certain study, the total effectiveness of patients after taking Vigabatrin ranged from 68.0% (after 2 months) to 70.8% (after 4 more months). These data show the potential of vigabatrin in controlling epileptic seizures.

Vigabatrin is particularly suitable for epilepsy symptoms such as partial seizures, generalized seizures, infantile spasms, and Landau-Kleffner syndrome. For infantile spasms, Vigabatrin can be used as an auxiliary treatment to help control spasms and reduce the severity of symptoms.

It should be noted that different patients may respond differently to Vigabatrin. Some patients may see significant benefit, while others may respond poorly or develop intolerance. In addition, the use of Vigabatrin is also accompanied by a series of side effects, such as drowsiness, dizziness, visual field defects, memory loss, etc. These side effects may affect patients' quality of life, particularly in pediatric patients, and require special attention to their potential long-term effects on visual field.

Vigabatrin is usually not used as a single treatment, but as an adjunctive treatment in combination with other anti-epileptic drugs or treatments. For a serious neurological condition like infantile spasms, a combination of treatments is often more effective.
